Alien Isolation is a WIP game for NES by sdm.

Release notes:

Code written at the beginning of 2019 (NESASM3, MMC1). I played with a code in which the opponent has a field of view. The code has bugs that I can’t fix and is simply badly designed, so it’s currently only a curiosity to play. In general, we control a player who must collect all the keys on several screens. We must avoid a Alien who can see and hear us. Small squares flying out of an Alien are his visualized field of view. The big square is the place where the Alien saw / heard us for the last time. The player has three walking modes: Standard (slightly affects the behavior of the Alien), running (Alien hears us) and sneaking (slow, but the Alien, unless he sees us, is unable to hear us). There are broken glasses on the ground that make a loud sound when we walk / run on them. Wooden crates protect us from Alien who cannot kill us there (When he chases us and we hide, after a while he will get bored and leave.)
